True inline 4″ high wheels–just like the ones used on Rollerblade skates–give these scooters the longest after-push glide possible. Includes steel frames with ball-bearing swivels and non-marring urethane wheels for indoor/outdoor use. Also includes safety wheel guards to ensure hands and fingers remain protected. Turbo Scooters™ are made in 12″ square and 16″ square handles models. Available individually in blue, red, or yellow; and in sets of 6 COLORZ.
